20718569 divided by 249 
The aim is to understand the frequency of 249 in 20718569.

Let's proceed to step 1:
249 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 249

Let's proceed to step 2:
If we divide 20 by 249, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 249

Going ahead to step 3:
249 can be fit into 207 0 times, resulting in a remainder of 207.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 207, we get 207.
Bring next digit (1) of the dividend behind the 207 and repeat the process: 2071 / 249

Going ahead to step 4:
If we divide 2071 by 249, we get 8 and a remainder of 79.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 1992 from 2071 to get 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 249

On to step 5:
When dividing 798 by 249, we get 3 with a remainder of 51.
The next digit of our result is 3. 
Result so far: 83.0
Subtract 747 from 798 to get 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 249

Going ahead to step 6:
249 goes into 515 2 times with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 832.0
Subtracting 498 from 515 leaves us with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 249

On to step 7:
249 can be fit into 176 0 times, resulting in a remainder of 176.
Put 0 as the next digit of the answer. 
Result so far: 8320.0
Subtracting 0 from 176 leaves us with 176.
Append the next digit (9) from the dividend to 176 and continue with: 1769 / 249

Going ahead to step 8:
1769 divided by 249 is 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 83207.0
Subtract 1743 from 1769 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
The number 249 fits into 260 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 83207.1
Subtracting 249 from 260 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
249 can be fit into 110 0 times, resulting in a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 83207.1
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 11:
If we divide 1100 by 249, we get 4 and a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 83207.104
Subtract 996 from 1100 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
When dividing 1040 by 249, we get 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 83207.1044
Deduct 996 from 1040 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 83207.1044 with a remaining 0.00044.
